Anyone hear about this?

It looks like a winner.

Yeah, but does it come in pink?

Seriously, though... winner is an understatement. That has a feature set that I really like.

I love the idea of switching calibers. I almost bought a EAA (Tangfolio) Witness 10mm (hunting legal cartridge) with the plan of getting 9mm and 40S&W conversions. Just seems efficient to me. The ARX100 hits the same chord for me.

I'm just waiting for it to be released so we can see some reviews.

To bad the .22 is the only thing available right now.  Read somewhere the .223 is gonna come commercial available next year.

Played with it up at SHOT show, but have not live fired one.  It is the civilian version for the US market.  A bit of changes from the ARX160 in the controls, but some changes are good and maybe not good IMO.  Hard to say as I have not been able to fire or even manipulate either for any lengthy amount of time.  Good is that the barrel change is amazingly simple and fast.  Quick to change left or right ejection and easy enough to change the charging handle from side to side.  Would prefer a non-reciprocating handle, but not that big of a deal and good that it swaps easily to either side.  Very much see the AR/M4 design ques in it.  One thing that I really didn't like from handling it was the bulk of the forend.  I think it will sell if they can keep the price set. 

Like the easy change barrels, looks kind of bulky though

It was rumored years ago that it was going to replace the AR-15 with the military.

The quick barrel swap is sweet but how many times will you use the left hand option if you are right handed or vice versa? It seemed like they were trying to emphasize that feature.

I believe learning to switch sides is very important especially when coming around different corners as it reduces the amount of your body that gets exposed.

I've actually been waiting for this gun for 2 years now beretta has been slacking saved up the money but just made an impulse buy on the tavor and xds in 9 mil
I'm gonna get the arx in fde for sure

In the middle of a firestorm will you configure the gun to left handed so you can hold it left hand and then switch it back when you need to shoot with your right? IMO, I think this feature is more for people who share the gun with left handed people. Don't get me wrong, I would still buy it.

Any word on what the price?

You had me at Beretta. 

Looks interesting.
The Beretta video on the OP's link says it's made in the USA and that you can change ejection direction with one button near the rear of the lower receiver.
Calibers? The video mentions .223/ 5.56 and .300 blackout.
Price?  http://www.gunsandammo.com/2013/06/06/at-the-range-beretta-arx100/ says $1,950
